Background: BRAVE Self-Help is an open access, iCBT program for the treatment of child and adolescent anxiety.The program has been accessed by over 72,000 Australian families, and although signifi cant reductions in anxiety symptoms are demonstrated following the program, the effects on life interference, or functional impairment are unknown.Aims: This study provides an overview of the uptake of the BRAVE Self-Help program in the Australian community and examines changes in both anxiety symptoms and anxiety-related impairment following participation in the program.Methods: Descriptive statistics will be utilised to show the uptake and use of the BRAVE Self-Help program in Australia between 1 July, 2014 and 1 March, 2023.A single group, pre-post study to examine changes in anxiety interference and anxiety symptoms was conducted in a sample of 1198 children (mean age 9.66 years) and 721 adolescents (mean age 13.66 years) participating in the BRAVE Self-Help program in Australia between 7 June, 2019 and 18 July, 2021.Results: Results demonstrated that both children and adolescents showed improvements in anxiety symptoms, with effect sizes ranging from  p 2 =.194 -.318.Children experienced reductions in life interference ( p 2 =.008 -.044), particularly later in the program, however adolescents did not show the same effects.In the low completer group (completing 3-5 sessions of the program), adolescents showed increases in at-home interference ( p 2 =.038).Conclusions: Self-help iCBT can bring about reductions in anxiety symptoms.However, young people, particularly adolescents, may require more sessions before entrenched life interference, can be overcome.
